  • Patent number: 7746115
    Abstract: A programmable logic device (PLD) data transfer cable includes a parallel interface, a programming interface, and a logic control circuit. The parallel interface is used for connecting to PLDs. The logic control circuit includes a first group of transmission channels, a second group of transmission channels, a first group of switches, and a second group of switches. The first and second group of switches control the working status of the first and second group of transmission channels respectively. The electrical connections between pins of the parallel interface and the programming interface when first group of transmission channels are activated are different with those when second group of transmission channels are activated.

  • Patent number: 7741119
    Abstract: A strain of xylose-utilizing Zymomonas was engineered with a genetic modification to the glucose-fructose oxidoreductase gene resulting in reduced expression of GFOR enzyme activity. The engineered strain exhibits reduced production of xylitol, a detrimental by-product of xylose metabolism. It also consumes more xylose and produces more ethanol during mixed sugar fermentation under process-relevant conditions.

  • Patent number: 7741084
    Abstract: Production of ethanol using a strain of xylose-utilizing Zymomonas with a genetic modification of the glucose-fructose oxidoreductase gene was found to be improved due to greatly reduced production of xylitol, a detrimental by-product of xylose metabolism synthesized during fermentation.

  • Publication number: 20100150983
    Abstract: An outer layer having an entanglement comprising an intermingling of cloaked hydrophilic guest and a hydrophobic polymer host, wherein molecules of the guest have been crosslinked with each other. Under certain circumstances, using complexes of the guest may be desirable or even necessary. The intermingling of the guest and host includes a physical tangling, whether it also comprises crosslinking by primary bonding (e.g., chemical/covalent bonding) there-between. Also a method of producing an outer layer having such an entanglement, including the steps of: temporarily cloaking at least a portion of the hydrophilic groups of the guest; intermingling at least a portion of the cloaked groups with a porous polymeric structure by diffusing the guest with cloaked groups into at least a portion of the structure's pores; within the pores, crosslinking at least a portion of the molecules of the guest with the guest; and removing the cloaking. Cloaking may be performed by silylation or acylation.

  • Publication number: 20100144041
    Abstract: An L-arabinose utilizing yeast strain is provided for the production of ethanol by introducing and expressing bacterial araA, araB and araD genes. L-arabinose transporters are also introduced into the yeast to enhance the uptake of arabinose. The yeast carries additional genomic mutations enabling it to consume L-arabinose, even as the only carbon source, and to produce ethanol. Methods of producing ethanol include utilizing these modified yeast strains.

  • Patent number: 7692000
    Abstract: A series of novel, melt- or mold-processable HA esters with varying aliphatic chain lengths are synthesized from silyl HA-quaternary (quat.) ammonium salt complex (preferably silyl HA-CTA, a silylated HA complex with cetyltrimethyl ammonium salt). Introduction of aliphatic acyl groups, preferably acid chlorides, to disrupt the strong HA intermolecular bonding, is done via acylation. Acylation takes place at the oxygen of the trimethylsilyloxy group —O—Si(CH3)3 in the silyl HA-CTA by removal of trimethylsilyl groups therefrom. Optionally, crosslinking may be performed during the shaping/molding of the HA esters into a structure/device, or thereafter, if at all. Native HA can then be regenerated/recovered by saponification hydrolysis, removing acyl groups, —CH3(CH2)10CO, and the cetyltrimethyl ammonium salt groups, -CTA, from HA ester. The structure/device of a preselected shape (e.g.

  • Publication number: 20100066410
    Abstract: Switching and repeating applications using an impedance matched source follower improve performance of high speed links such as PCI Express, HDMI, DisplayPort and DVI by reducing attenuation and other degradation of high speed signals, including those with transmit pre-emphasis, by avoiding impedance discontinuities over process, voltage and temperature variations and by driving a broader range of loads, e.g., heavily capacitive loads. A circuit for switching or repeating signals on a single-ended or differential high speed link may comprise a source follower with input and output impedances matched to input and output transmission lines on the high speed link. The source follower is biased by a constant transconductance circuit, an external calibration circuit or other circuit to provide an essentially constant output impedance over process, voltage and temperature variations.

  • Publication number: 20100066404
    Abstract: A reduced power differential type termination circuit for use in SSTL, HSTL and other transmission line systems reduces power consumption. A differential type termination circuit may comprise first and second nodes for coupling, respectively, to first and second transmission lines; a first impedance coupled between the first transmission line and a third node; a second impedance coupled between the second transmission line and the third node; and a low direct current reference voltage generator for generating a reference voltage applied to the third node. The first and second transmission lines may transmit complimentary signals. The first and second impedances may be symmetric or asymmetric. The first impedance may match the second impedance. The first and second impedances may, respectively, match the impedances of the first and second transmission lines. The first and/or second impedances may include a bidirectional switch, such as a transmission gate, to enable and disable the termination circuit.

  • Patent number: 7629156
    Abstract: Xylose-utilizing Z. mobilis strains were found to have improved ethanol production when grown in medium containing mixed sugars including xylose if sorbitol or mannitol was included in the medium.

  • Patent number: 7598627
    Abstract: A switch-mode power supply for selectively providing power from a main power source and a standby power source to an electronic device is provided. The switch-mode power supply includes a signal input, a first transistor, a second transistor, a driving circuit, and a switching circuit. The signal input is used for receiving a control signal. The driving circuit and switching circuit connect the signal input to the gate of the second transistor in series. When the driving circuit detects the first transistor is switched off, the gate of the second transistor is immediately pulled up to open the second transistor, and when the driving circuit detects the first transistor is switched on, the gate of the second transistor is immediately pulled down to close the second transistor.
